. the following is a specification.

My invention has for its object the production of a particularly simple and eiiicient means tor controlling the movement of ra1l-, way vehicles, and to this end, it conslsts in l the combinations and constructions hereinafter set forth and claime In describing this invention, reference is bad to the accompanying drawing, in which like characters designate corresponding parts in all the views.

Figure 1 is a partial sectional view showing my ap aratus adapted to a locomotive Figs. 2 an 3 are, respectively, longitudinal and vertical sectional views of this apparatus.

p This invention comprises means, operated by the motive fluid from the train pipeof an automatic brake system of a railway vehicle, for automatically shutting OK the motive power of the vehicle, and also for controlling the application of the brakes, and electromagnetic means for controlling the flow of the motive fluid from the train pipe, to the former means, the latter means being governed in its operation from the road-' bed here illustrated, I haveshown my invention as applied to a locomotive.

1 is the steam dome; 2 the throttle valve, and 3 the throttle lever. Said lever is connected to the valve 2 by suitable means as a -rectilinearly movable power-transmitting link or member 4, and a bell-crank lever 5.

6 is the train pipe of an automatic brake system, in which the brakes are applied when the motive fluid, as compressed air is free to escape. In addition to the train pipe, said brake system includes a main reservoir 7 for supplyin motive fluid through the train 'pipe'to t e auxiliary reservoir, and

also the usualtriple valve and the brake cylinder of each ran the auxiliary reservoir, triple valve-and'dirake cylinder may be-of any suitable construction, and form no part of this invention, illustration or de- 'scription thereof is deemed unnecessary.

8 is the engineers valve for controlling the flow of the motive fluid through the train pipe 6 to the auxiliary reservoirs, not illussage 13 opening into one end of the piston chamber 10 and extending crosswise of one end of the chamber 12 and connected to the train pipe 6, a guide 14: extending axially from the chamber12, and opening into the inlet passage 13, a piston 15 movable in the chamber 10 and connected to the throttle valve 2, an electromagnet 16 arranged in the chamber 12, the terminals 17 and 18 of the magnet being in circuit with contact pieces 19 and 20 adapted to engage conductors along the road-bed, and an armature 21 slid able in the guide 14, and serving as a valve for the inlet passage 13, the armature being normally in position to close said passage. The piston 15 is connected directly to one end of the member 4 of the throttle valve mechanism, and is normally arranged between the outlet and inlet passages -.11 and 13, so that after it has traveled a suificient distance under the pressure of themotive fluid to close the throttle valve 2, such fluid can escape through the outlet passage. Said member 4 usually extends axially into the; piston chamber 10 and is formed with a socket 22 in its inner end in which projects a 'rod' 23 extending axially of the piston and the piston chamber, and connected to the throttle lever 3.. This rod 23 abuts against the inner wall of the socket -22 of the member 4 when the throttle lever 3 is operated to close the throttle valve 2, but the member 4 and the piston 15 are capable of movement relatively to said rod 23, as when moving under the pressure of the motive fluid flowing from the train -pipe through the passage '13, it being understood that the throttle lever 3 is provided with the usual pawl and rack for holding it in its adjusted position.

Friction means are provided for clutching the piston 15 to the rod 23, in order that after the piston has been moved b the motive fluid, the throttle lever 3 may e pushed inwardly and a sin pulled out to bring the piston with it En the purpose of releasing the brakes and opening the throttle valve.

As shown, the piston 15 is formed hollow,

and spring-pressed friction shoes 24 are located within therod 23. p

After the armature 21 has been attracted piston and engage the by the magnet 16, it may be returnedto-its original position by means of' the hand' lever-z. 25. As here illustrated, the. conductors iwithl which the Contact pieces 19 and 20-enga e, are preferablyfan insulated section-260i? t e' track, and a third rail-'27 extending along the track. These conductors are thrown mto connection with a suitable source of supply.
